Door linedef types
A door is a sector, usually placed between two rooms, whose ceiling raises to open, and lowers to close.
A door is fully closed when its ceiling height is equal to its floor height.
A door is fully open when its ceiling height is 4 less than the lowest neighbor ceiling adjacent to it.
A door may be set to an intermediate state initially, or thru the action of a linedef trigger that affects ceilings or floors. The door is passable to a player when its ceiling is at least 56 units higher than its floor. In general the door is passable to a monster or a thing when its ceiling is at least the monster or thing's height above the floor.
If a door has a ceiling height ABOVE the fully open height, then an open door action moves the ceiling to the fully open height instantly.
If a door has a ceiling height BELOW the fully closed height (that is the ceiling of the door sector is lower than the floor of the door sector) a close door action moves the ceiling to the fully closed height instantly.

Door functions
- Open, Wait, Then Close
On activation, door opens fully, waits a specified period, then closes fully. This door type is also known as a "Raise" door.
- Open and Stay Open
On activation, door opens fully and remains there.
- Close and Stay Closed
On activation, door closes fully, and remains there.
- Close, Wait, Then Open
On activation, door closes fully, waits a specified period, then opens fully.
- Wait, Open, Wait, Close
Available as a parameterized line special only, this door type waits for a specified countdown period, and then functions as a normal "Raise" door.
- Wait, Close and Stay Closed
Available as a parameterized line special only, this door type waits for a specified countdown period, and then closes fully and remains closed.
Varieties of doors
A door can be triggered by pushing on it, walking over or pressing a linedef trigger tagged to it, or shooting a linedef tagged to it. These are called manual, walkover, switched, or gun doors resp.
Since a push door (P1/PR) has no use for its tag, BOOM has extended the functionality to include changing any tagged sectors to maximum neighbor lighting on fully opening, then to minimum neighbor lighting on fully closing. This is true for regular, extended, and generalized doors with push triggers. Parameterized push doors use a separate argument to control dynamic door lighting.
A door trigger can be locked. This means that the door function will only operate if the player is in possession of the right key(s). Regular and extended door triggers only care if the player has a key of the right color, they do not care which. Generalized door triggers can distinguish between skull and card keys, and can also require any key, or all keys in order to activate.
A door can have different speeds, slow, normal, fast or turbo. Parameterized doors can open at any speed.
A door can wait for different amounts of time.
A door may or may not be activatable by monsters.
Any door function except Close and Stay Closed, when closing and encountering a monster or player's head will bounce harmlessly off that head and return to fully open. A Close and Stay Closed will rest on the head until it leaves the door sector.

There are two generalized door linedef types, Generalized Door, and Generalized Locked Door. The following tables show the possibilities for each parameter, any combination of parameters is allowed:
Slow and Fast represent the same speeds as slow and fast regular doors. Normal is twice as fast as slow, Fast is twice normal, Turbo is twice Fast.

There are currently six types of parameterized door specials, each performing a different type of door action. See the Parameterized Door Types section for full information on how to use these specials.
